and useful Improvements in Gas-Producers,

of which the following is a specification.

This invention relates to improvements in gas producers havingmechanically operated grates capable of crushing clinker and ofdischarging clinker and ash at regular and regulative rates, and has forits object to effect more perfectly than heretofore the control anddisposal of clinker and ash discharge from the gas producer.

In carrying out my invention, and with reference to the accompanyingdrawings, Figure 1 is a sectional elevation of a singlechambered gasproducer provided with an ordinary fixed grate of inverted type, andarrangement of crusher rolls in relation thereto according to one formof my inven- 'tion.

Fig. 2 is a sectional view at right angles with Fig. 1, and in whichother parts having reference to my invention are included. Fig. 3 is ahorizontal cross section through line a0, a2, of Fig. 2.

Fig. 4 shows in outline and in elevation a battery of producers, withthe application of a number of water channels thereto.

Fig. 5 is a plan view of Fig. 4, with a detail added. Fig. 6 is a singleproducer in outline with the water trough indicated at the part shown insection. Fig. 7 is a detail, on another scale, having more particularreference to Fig. 3.

a is a form of producer, of circular shape, about a diameter of which isa fixed grate b of the inverted V type.

A cover or member 0 is shown at right angles with the axis of the grate,which, with the latter, divides the area of the base of the producerinto four quadrants or sectors, or approximately so. For each of theseso called quadrants there is shown to be a pair of crusher rolls mountedbelow the level of the bottom edge of the grate b, and situated inparallel formation. The rolls of one quadrant are, however, disconnectedfrom the rolls of another quadrant; thus, the pair of rolls shown at clare independent of the pair. of rolls shown at e, as well as of thepairs of rolls shown at k and Ya. In Fig. 1, the shafts upon which therolls 4 and e are mounted will clearly be seen to be disconnected at thecenter line of the producer in the plane illustrated. These shafts arehere provided with worm wheels Z in gear with Worms m, (see Fig. 7)similar worms and wheels being used for all the rolls. Thus one pair ofrollers may be rotating when another pair is at rest. In Fig. 7, a pairof worms mare shown attached to common shaft 1, in gear connection witha shaft 4 bv meansof gear wheels 2 and 3, shaft 4: being driven from asuitable source of power.

The divisional member 0 is here formed as a cover to protect the endbearings of the rolls at that part, and also to bridge over the gapbetween adjacent ends of said rolls.

Each pair of rolls is arranged so that the two rotate when in motiontoward each other, in order to draw in the clinker to be crushed, as iswell understood, and it is desirable that these rolls be of substantialdiameter such as indicated by the proportion illustrated, so as toinsure the material being drawn between the same in a satisfactorymanner. But each pair of rolls is capable of independent motion,according to the source of power in connection therewith, so that one ormore pairs may be in motion when others are not; or, the motion of onepair may be of a different or regulative rate compared with that ofanother pair.

Each producer shown is provided with a water trough u, in the shape oftwo parallel channels of V form, the apex thus produced between them ineach case being centrally situated, such as indicated in Figs. 2 and 4.The water lutes of the channels may have a level slightly below thelevel of the axes of the rolls 0?, 6, 7t, and 7:, as indicated by brokenline in Fig. 1, and the channels themselves are preferably inclined,(see Fig. 6), toward a main conduit such as in Figs. 5 and 6. Anysuitable form of conveyor such as a traveling bucket system as atposition 0 in Fig. 4: may be adopted for the removal of the ash andbroken clinker. To insure the same being effectually propelled into themain conduit, or out of the channels u, I provide hydraulic means suchas pipes '11 (Fig. 2) capable of operating at their oriflees in thewater lutes as jets when supplied with water at suitable pressure.Similarly the material may be propelled along the main conduit forremoval at one extremity.

By the means described, it will be seen that, the rolls when immersed toa large extent in the water lutes, or continuously in contact therewithduring complete rotation, are kept comparatively 0001 during Working;the independent control of the movement of pairs of rolls makes themselective area for area in Which they are situated or enables thecondition'of the combustion zone of the producer to be largelyregulated; and the application of hydraulic jets for removingaccumulated ash and crushed clinker, enables the crusher rolls to befree for operation, besides insuring a rapid and satisfac tony method ofremoval above named.

lVith Water bottomed producers in Which is employed low grade high ashcoal it is impossib1e=to remove the ash and clinker by hand, andhydraulic means as described enable this to: be accomplished eflectivelyprovided the materialto be removed is comparatively small. The crusherrolls for breaking up the same previously are thus essential, and Whichresult is better attained in the main by the use of the pairs of rollsin different sections of the grate area operating as described.

I claim In combination, a Water-bottomed gas producer, a grate areadivided by members into distinct areas or sectors, a pair of crusherrolls in each area aforesaid, one pair of said crusher rolls capable ofmovement when other pairs are atrest, a Water lute below said rolls andin continuous contact with them, and Water pipes leading from said lutesfor hydraulic removal of the ash and clinker, substantially as hereinset forth.

In testimony whereof I have afiixed my signature.
